THREE-DEMENSIONAL LOGICAL TRANSLATION TOY

摘要

A closed, transparent, cubic box (1) contains twenty-six cubes (2) and a vacant cubic space (3) into which the small cubes (2) readily slide when the box (1) is tilted. A central core consists of seven small cubes permanently interconnected while the other nineteen are slidable. In the basic position, the faces of the small cubes (2) lying outermost and adjacent the inner wall of the box (1) have the same colour e.g. red, while all other faces are of a different colour. The task is to restore the cubes (2) into the basic position in which only red faces can be seen. A less exacting version has a 2 x 2 x 2 box filled with seven cubes. The number of colours or markings may be varied or transparent cubes may each contain part of a sculpture. The box (1) may be partially opaque.
